  • Patent number: 8736163
    Abstract: An organic electro-luminescence display device and a method for fabricating the same are provided. A first substrate and a second substrate are sealed by a sealant. An organic electro-luminescent diode is formed on the first substrate. The sealant contains a frit glass and a light-heat converter. The frit glass can reduce the moisture and oxygen transmission rate by preventing the organic electro-luminescent diode from being thermally decomposed during a curing process. Since the two substrates are encapsulated by the frit glass, the lifetime and reliability of the organic electro-luminescence display device can be increased.

  • Patent number: 8274636
    Abstract: A method of forming a spacer for a liquid crystal display (LCD) device is disclosed. To form the spacer, an ink jet injection nozzle is aligned over a substrate on which unit pixels are arranged in a matrix. After aligning the nozzle, first dispensing spacers are dispensed from the injection nozzle with a certain gap so that at least one unit pixels is interposed between the spacers. Subsequently, the nozzle is moved and second dispensing spacers are dispensed by the nozzle at each of the unit pixels formed between the first spacers. This is repeated until the spacer is formed at all unit pixels. The spacer contains a ball spacer and a volatile liquid, which is vaporized during dispensing. The ink jet injection method prevents adjacent spacers from interfering with each other during formation.
